Trillion: God of Destruction
The game takes place within a demonic hell separated into six layers. The Demon King Zeabolos, having previously lost against a battle with Trillion, makes a deal with a grimoire-wielding girl by the name of Faust. In exchange for Zeabolos' soul, Faust grants him his life, and he travels to fight against Trillion again alongside six Demon Lords. These Demon Lords, each with the appearance of a young girl, go by the names of Luche, Levia, Fegor, Mammon, PerPell, and Ashmedia. Ten different endings are possible based on the choices of the player. [Wikipedia]
